ResumoThe ratio of the masses of He and ${\mathrm{H}}^{1}$ was measured by comparison of ${\mathrm{He}}^{++}$ with ${\mathrm{H}}_{2}^{1+}$ on fourteen spectra, and the measurements give He: ${\mathrm{H}}^{1}$=3.971283\ifmmode\pm\else\textpm\fi{}0.000042. If He=4.00216\ifmmode\pm\else\textpm\fi{}0.00013 on the ${\mathrm{O}}^{16}$ scale as given by Aston, then ${\mathrm{H}}^{1}$=1.007775\ifmmode\pm\else\textpm\fi{}0.000035 in excellent agreement with the value 1.00778 reported by Aston. A method is suggested for the determination of the mass of ${\mathrm{H}}^{2}$ in terms of He and C.
